' Specification forming part of Letters Patent No. 52,597, dated February 1866.

To all whom, it may concern:- i I Be it knownthat I, I. N. PL01Ts,-0f New York city, have invented new and useful Iin proveinents in. Buckles or Belt Gla-sps; and I do hereby declare that the following is-a full, clear, and exact description thereof, which will enable those skilled in the art to make and'usethe same, reference being had to the acc'om' 'ia-nylng drawings, forming part of this specification.

This invention relates to certain improve ments on a'- buckle or belt-clasp for which- Let.

ters Patentof the United States were-issued to me on the 7th day of November,'1865.

The nature of the present inventions consists in setting or raising the inner edges of the bars of the buckle above the plane of the face of the buckle, so as, when the/strait is drawn taut, to produce'a sharp'bight or'he'nd of the straps under the side strips of the frame of the enckle also, in settin g or depressingthe inner gs of the side stripsof the buckle-frame below the plane of the under side of the buckle.

to effect a similar purpose; also, in attaching to orformm g upon the inner edge of theside 'st'ripsaprojecti'ng lip or lips, over the edges ofwhich the straps pass, by which construction of the buckle, whether the above features The several features of my invention are.

illustrated in the accompanying drawings, in

Figure 1 is a front view of niyduplex buckle, showing its application to its straps. 2 1s a front view of my single buckle, showing its application to its straps. Fig.3 is a transverse section of a duplex buckle, showingthe inner edges of both'longitudinal bars thrown upward or raised above-the plane of the face ot" the buckle, also showings projecting lip,

substantially the sanieas'was shown in myaforesaid patent, formed on the outer edges o the sides. of the buckle, designatedyonthe drawings No. I. is a. transverse-section of. the single buckle, showing one edge of its central barra'ised or thrown upward, as in the precedin duplex example, and a lip, such as was shown in my aforesaid patent, on the outer edge of the side which-receives the loose strap, designated No. 2. Fig. 5 is a.- transverse section of the duplex buckle, showingthe'inner edges of its longitudinal bars thrown upward toward each'other-that is,-at right angles in opposite directions to each other-''and having (On this lips, designated .No. 3.)

its longitudinal bar raised or thrown upward,

and the inner edge of one side'ot the frame (that next the loose strap) depressedor thrown down,,so as to answerlthe purpose of a lip,

designated No. 4. Fig. '7 is a transverse section of Fig. 1, showing the inner edges of the longitudinal bars raised or thrown upward toward each other, and the frame grooved or curved all around, thus providing good bitingedges on both side strips of the frame of the buckle, designated No. 5. Fig. 8 is a transverse section of Fig. 2, showingt-heedge ot' the bar thrownupward. and the frame grooved all around,as in Fig.7, designated No. (i. Fig. 9 is a'tra-nsnerse section of the duplex buckle, showing the inner edge of itslongitudinal bar raised or thrown upward and lips formed on the inner edges of the sidefstrips'ot' the frame, designated- No. 7 Fig. 10 is a transversesection of the single buckle, showing its bar raised or thrown upward and alip formed-on the inner edge of the side nearest the loose.

Similar letters of reference indicate corresponding parts I 7 lllhe buckle is made, in its principal features, the same as that which'fornied the subject of the patent granted to me, beforealluded to, A A being the plate or frame of the buckle, and B the longitudinal bar or bars left after removing the pieces to form the slots a, a.

Those merked'c are thescm'e as those shown in my previous; patent. Those c! are placed on the inner edges of 'the side strips ofthe buekle--tha,t is, the; project out at about right angles to the plane of the under side of thebuekleplate. llhe edges of the lips, es
